QUARTZ TRANSPORTATION LLC: RANCHO CUCAMONGA, California Trucking Company
QUARTZ TRANSPORTATION LLC is a mid-size fleet operating out of RANCHO CUCAMONGA, California with USDOT number 3168539. The company operates 38 power units and has no published FMCSA safety rating (most active carriers are unrated unless they have undergone a compliance review). Based on our analysis of federal safety data, QUARTZ TRANSPORTATION LLC has a FileFlo Carrier Intelligence Score (CIS) of 39/100, classified as High Risk.
FMCSA Safety Record & Inspection History
QUARTZ TRANSPORTATION LLC has undergone 50 recorded DOT inspections. The vehicle out-of-service rate is 30.0%, which is above the national average of 20.72%. This elevated rate indicates potential maintenance or pre-trip inspection deficiencies that could lead to roadside violations. The driver out-of-service rate is 6%, above the national average of 5.51%. Common causes include hours-of-service violations, expired medical certificates, and CDL issues.
Recorded Violations and Out-of-Service Status
The public FMCSA record for QUARTZ TRANSPORTATION LLC carries 73 recorded violations, and the most recent inspection on file is dated October 13, 2026. Across 50 recorded inspections, the record carries 3 driver out-of-service violations and 19 vehicle out-of-service violations.
A recorded violation is what an inspector wrote down at the roadside. It is not a penalty, and it is not an amount owed: FMCSA assesses civil penalties only after a compliance review classifies specific cited violations. The step that changes this record is the document behind each line, so the next move is to see which records an investigator would ask for and which of them exist today.
What a 39/100 Carrier Intelligence Score Means
The Carrier Intelligence Score is FileFlo's own summary of three public FMCSA components for QUARTZ TRANSPORTATION LLC: the safety rating, the inspection pass rate and the out-of-service rate against the national average. It is not an FMCSA score, and FMCSA does not use it to choose carriers for an investigation. 39 out of 100 falls in FileFlo's High Risk band.
Authority Type, Hazmat Status, and Operating Profile
QUARTZ TRANSPORTATION LLC is classified by FMCSA as an interstate carrier.
The carrier holds an Authorized For Hire classification, meaning it transports cargo or passengers for compensation under FMCSA operating authority and is subject to MC-number requirements at 49 CFR Part 365.
QUARTZ TRANSPORTATION LLC is not flagged in FMCSA Census as a hazmat carrier (HM indicator: N), so the carrier is not subject to the additional 49 CFR Subchapter C hazmat regulations.
Operational range per MCS-150 filing: interstate beyond 100 miles (long-haul, 11 drivers); intrastate within 100 miles (27 drivers). The 100-mile boundary matters because drivers operating within a 100-air-mile radius qualify for the short-haul exception under 49 CFR 395.1(e)(1), which removes the requirement to maintain RODS for the day.
Self-reported MCS-150 annual mileage: 1,513,946 miles. MCS-150 mileage feeds the FMCSA SafeStat exposure denominator: drastically understated mileage can artificially inflate CSA BASIC percentile scores by reducing the per-mile exposure baseline. Updates are required every 24 months under 49 CFR 390.19.
Fleet Composition and Driver Profile
Owned equipment per the FMCSA Census filing: 32 tractors. Owned-vs-leased equipment matters for compliance documentation, owned trailers require the carrier to retain annual inspection certificates under 49 CFR 396.17, while leased trailers shift that documentation responsibility to the lease agreement.
The carrier reports 38 CDL-holding drivers on file. Each CDL driver must have a current Driver Qualification File (DQF) maintained per 49 CFR 391.51, including a Medical Examiner's Certificate, an annual MVR review, and a record of road-test results.
Intrastate driver count: 27. Intrastate drivers may be subject to state-specific CDL endorsement and hours-of-service variances depending on the state.
FMCSA Crash History
The FMCSA Motor Carrier Management Information System (MCMIS) crash dataset records 14 crash events involving QUARTZ TRANSPORTATION LLC in the available reporting window. Of these, 1 involved a fatality, 7 involved a reported injury, and 14 resulted in a tow-away. 14 events meet the federal-recordable threshold under 49 CFR 390.5 (fatality, injury treated away from the scene, OR tow-away of any vehicle).
Most recent recorded event: OLYMPIC/LEMON, LOS ANGELES, CA on April 29, 2025.
QUARTZ TRANSPORTATION LLC's Inspection Fingerprint: Geographic Pattern and Trend
Inspections cluster geographically across California (48), Arizona (2). The concentration in California is consistent with the carrier's primary lanes and tends to correlate with which state DOT inspector teams QUARTZ TRANSPORTATION LLC's drivers encounter most often at roadside checkpoints.
